To all whom, itm'ay concern 1;

'Be it known that we,'D1LLwiN MXBELL,

and J OI-IN C. FOGARTY, citizens of the'United States, residing at Chicago, in the county of Cook and State of Illinois, and Green Bay,

in the county of Brown and State of Wisc'onsin, respectively, have invented a certain new and useful Improvement in Paper- Serving 'Machines, of which the following is a full, clear, concise,"'and exact description.

Our invention relates to aper serving machines of the type. which iolds a bunch of sheets of paper and delivers the sheets, one at a time, from an inclosingcasing.

It constitutes an improvement upon United States Patent No. 604;,113, granted May 17th, l898,'upon an application of The objectsof our invention are; to provide a paper serving'machine of the type mentioned, in which the delivery of the successive sheets is more certain and assured than heretofore; inwhich the case is so closed that it is proof against being tampered with from the outside; which maybe readily refilledwhen the paper supply is exhausted; and which lends'itself to economsical manufacture- In the accompanyin illustrated the preferred invention; I I g Figure 1 is an elevation partly in section taken on the line 1 -1 of Fig, 2; Fig.

drawings we have elnbOdll'HBIlhpf the 2 is a sectional elevation on the line 2-2 of Fig. l; and Fig; 3 is an elevation of adetail.

The casing comprises, generally speaking;

two hingedportions, the rear portion 1 being adapted to be secured to a suitable support and constituting the body of the casing, and

the front portion 2 constituting the *cover' therefor, said front and rear portions being hinged to each other at thepoint 3, andnormally locked in closed position by a suitable lock 4, which may be of any standard construction. Within the body of the casing a friction roller 5 is rotatably mounted, said roller in its preferred form consisting of a wooden cylinder having'preferably a. plurality of friction bands 6 of rubber fabric, or other suitable material, encircling the same. Said roller is fixed to a suitable spindle 7, the latter having at one end a knurled knob or handle 8, whereby the roller may be readily rotated directly by hand if the cover."

necessary, "and having'at th other 911a fab? ratchet 9 1 adaptedto cooperate with v a suitable pawl-1O to. prevent backward rotation of theroller. The pawl10 is pivotally supported on the casing 1 and is provided with a projecting lug 11 which is received with-' v in a slot 12 in thesaid casing, said lug and slot limiting the movement of said ratchet,

The spindle 7 is received'atopposite ends within a pair of diagonally extending'slots 13 arranged in the sidewalls of the casing 1. Said spindle rests against the lower ends of said slots as seenin Fig. 2. It is locked in said positionaby the casing'2 when the latter is closed, said casing having in one side wall a "slot le'arranged on an arcdrawing throgh the hinge 3 as a center and, having in the other side wall an arc-shaped recess 15' pT S' d Out of the metal" and performing a vii g will beapparentfrom-Fig. 2, the spindle 7 I I 1:

function similar 1 to 1 that of the slot 14. As

is firmly locked against movement inany direction when "the casing is closed. \Vhen the cover is thrownopen, the. spool with itsspi'ndle may be readily lifted out ofjthe j diagonal slot and replaced with equal ease. h

The pawl and ratche't 9 and-"3'10, although arranged on the outer side wall of' the casing lit) proper 1,'are, nevertheless,inclosed'within 1 the'pressedputchannel16in the "side wall of A bunch or package 1 7 of sheets of paper is arranged within the casing as shown in FigxQQthat is, it is bent or hung over the roller with th'usujal securing wire 18 at 1 one endthereof hooked onto a suitable catch l9, the'latter being preferably an olfset projection 'on a pivoted shield '20 having a pair of oppositely extending projections or lugs 21 received-within sultablegopenings in the side wall of: the casing proper and constitut ing pivotal supports for said shield.

;The opposite end of the package of paper 17 has afbeveled appearance thatl is, the

sheets nearest to the roll 5 are bent through an arc of the smallestradiu's' and hence hang down lower than the outer sheets," which are bent through an arc of larger radius. The lower ends of said sheets rest against a suit: able guide-plate or d'elivery-plate 22 which maybe mounted within the casingin any suitable manner, and'which extends forward In the construction disclosed, it is securedla't one end by books 23 struck up from the'metal of the casing. It

\ be drawn downwardly by hand and removed v in contact with said roller. The next adcasing, said opening being one through" which a single sheet at a time is adapted to project, whereby the successive sheets may from the casing. The shield 20 also projects into saidopening and preferably slightly through it, as shown in Fig. 2. In order to adjust the device for operation after a package of paper has been inserted, the knob 8 is turned slightly whereby the friction between the bands Band theinner sheet of paper causes the latter to be advanced by the roller, thereby tearing it loose from the securing wire 18 and causing the lower end thereof-to project a slight distance through the opening 28 beyond the end of the shield 20. In this position said sheet may be readily grasped by hand and withdrawn from the casing. Such withdrawal will serve to rotate the roller 5 whereby the next adjacent sheet is torn loose an'dca-used to project through said opening, whereby it may be withdrawn subsequently in the same manner as the first sheet. It,1-wiil :be seen that the roller 5 is rotated by the sheet which is being withdrawn by hand, only so long as the inner end of said sheet remains jacent sheet is advanced, therefore, only during the brief interval that the friction band 6 is rotating in contact therewith. This interval. corresponds to the rotation of the roller through an angleof perhaps l80 or less as the inner end of an iven sheet is being withdrawn from over the roller.

In order to insure the holding of .the ;pack-' age of paper against the roller and thereby increase somewhat the friction between the roller and the adjacent sheet, I provide a suitable arm v29 which is fixed to a supporting tlOCl 30, the latter being mounted at oposite ends in theside walls of the cover 2.

aid rod may have aflixed thereto at one end and outside of the cover a suitable pointer or indicator 31 which will move gradually-with the arm 29 through a small are as the successive sheets are withdrawn, due to the decreasing thickness of the remaining package of paper. A glance at said pointer will indicate in a general way the amount of paper remaining, whereby a new package may be inserted when the receptacle becomes empty. The arm 29 is bent downwardly at itsforward end as shown, whereby when the cover is opened said arm projects nearly'at right angles from said cover and accordingly when the cover is closed the other end of said arm, which is curved upwardly, rides freely over the curved package of'paper without having to be manipulated and without catching on the same.

The shield v20 has the effect of reducing the efiective'size of the opening 28 to a narrow slit, just suflicient to permit the exit of a single sheet of paper. Said shield nor mally tends to close said opening, but, as there is usually at least a single sheet of paper projecting therethrough, said opening is never entirely closed, except when there is no paper whatever in the receptacle.

,It will beseen that the wire 18 is connected with the catch 19 at a point ofiset somewhat with respect, to the shield 20. Accordingly whenever any paper is being drawn from the receptacle and the roller 5 is rotating, there is .a slight tension or pull on said wire 18 which tends to rock the shield 20 outwardly, thereby releasing the friction on the paper .as it is being .drawn through the opening. its thepaper may be of thin tissue, which tears very readily, this automatic release of the pressure thereon insures the removal of the entire sheet without mutilating it.

Through ignorance or maliciousness it has been the practice in prior instances, where a paper feeding receptacle of this character has failed .to operate so as toleave a protruda ing sheet, to insert aknife or some other .ob-

ject and endeavor .to'drag the next sheet out,

thereby mutilating the paper and often disarranging the device so as to obstruct the further satisfactory operation in the intended manner. The main function of the shield turning the knob than !t() attempt other expedients when there is no protruding sheet of paper waiting :to be grasped. The knob cannot be turned the wrong way by virtue turning thereofin the only direction permitted will advance .a sheetat any stage of the operation.

From the above description is will be seen that we have provided a device wherein the normal operation, namely the partial advance of anyone sheet by the withdrawal oiithe preceding sheet, is positive and relia e.

of the pawl and ratchet mechanism, and the We have provided further, means whereby if for any reason a sheet should not i be left protruding from the receptacle the obvious thing .to .do' is to turn the handle 8, which willadvance the sheet in the desired manner, after which the normal operation will be continued. We have provided furthera device in which unauthorized tampering with the interior mechanism is prevented, all theparts being inclosed and protected and locked by a single lock. The insertion of knives or other objects into the feed slot next sheet to protrude therefrom, and a pivoted shield adjacent said opening and adapted to restrict said opening to a size necessary to permit the issuance of the desired sheet, said shield cooperating with said paper in such a manner as to tend to relieve its pressure on the issuing sheet as it is being drawn from the receptacle.

2. In combination, a casing and cover hinged thereto at its lower end and having anopening therein, a diagonally'arranged guide plate within said casing, said guide plate extending to said opening, a friction roller, a spindle therefor, said spindle projecting through slots in the sidewalls of said casing, an arc-shaped slot in said cover curved about the pivotal connection as a center, said slot being adapted to receive one projecting end of said spindle, a handle-on said projecting end, a ratchet on the opposite end of said spindle, said ratchetbeing received within a pressed'out channel in the cover, whereby said ratchet and its cooperating pawl are-inclosed thereby, a shield pivotally supported within .said casing. and extending to-said opening, an offset projection on said shield whereby one end of a package of paper bent around said roller may be secured to said projection and thereby tend to swing said s iield when tension is applied to said paper, and'a friction arm 5 suitably mounted in said cover and adapted to press said paper against said roller.

In witness whereof, we hereunto subscribe our names this tenth vday of March, vA. D.,
